TABLE OF CONTENTS The E-field probe comparison has allowed us to formulate several conclusions regarding the optimization of antenna types used in them. The conclusions are, in some sense, evident but the most important are the approaches that may be used by meter builders when the probes are planned and designed as well as their users for evaluation and comparison of meters available on the market.
However, the most important thing is the possibility of estimating the measurement accuracy that is a function of all accuracy limiting factors discussed in this chapter. In addition, other factors that are independent of the particular needs of a measurement, should be found, defined, estimated and included in the resultant evaluation of the measurement inaccuracy by the reader.
There is a possibility of almost arbitrary shaping of the frequency response of a wideband probe by the appropriate choice of the corner frequencies of the filters used in shaping the response. For instance, based on the permissible magnitudes of errors ? 1E and ? 4E, it allows remarkable limitation of the probe's sensitivity at frequencies outside the measuring band. On the other hand, the errors resulting from the accepted relations of R 0/h and h/ ? determine both the properties of the probe with a selected type of the measuring antenna and the applicability of the probe in the near-field measurements. Consequently, we devoted most of our attention to their analysis.
The errors ? 1E, ? 2E, ?
